God created the possibility of evil; people actualized that potentiality. The source of evil is not God's power but mankind's freedom. Even an all-powerful God could not have created a world in which people had genuine freedom and yet there was no potentiality for sin, because our freedom includes the possibility of sin within its own meaning.
Peter KreeftThe church is: a conspiracy of love for a dying world, a spy mission into enemy occupied territory ruled by the powers of evil; a prophet from God with the greatest news the world has ever heard, the most life changing and most revolutionary institution that has existed on earth.
